puppet-keystone fails on EL6 with Ruby 1.8.7

[Erik McCormick]

Attempting to run the stable/liberty version of puppet-keystone throws errors on Centos 6.7 running puppet 3.8.6 and Ruby 1.8.7.

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not autoload puppet/type/keystone_tenant: /etc/puppet/environments/rwdc1prod/modules/keystone/lib/puppet_x/keystone/composite_namevar/helpers/utilities.rb:17: syntax error, unexpected '.', expecting ']'
              .zip(required_resources)]
               ^

                    .map { |namevar| existing.send(namevar) }
                     ^

I built a new master on Centos 7 with the same puppet version and the stock Ruby 2.0.0 and everything works perfectly.

We do not support el6, neither Ruby 1.8 as far I know.

I'm not sure we'll patch composite_namevar to support old versions of Ruby, but your bug is still valid.
